I'm convinced now that this is either in the resonator or adjacent to the exhaust on the body since we're both hearing the same exact thing.
I purchased a welder thinking a spot weld on the MRT tips broke and i was going to fix it this weekend but now I'm pretty sure it's going to be something internal to either the resonator or not part of the exhaust system at all.
edit: fyi, when i refer to "resonator" i'm referring to the stock x pipe "resonator" and not the secondary cats like some exhaust manufacturers are doing. (attached a picture of a stock system - not mine - pointing out where I believe the source of the sound is coming from now)
Looks like there are no aftermarket options for X pipes for the V6 that dont also require deleting the secondary cats - which is not federally legal and not something I can depend on getting away with where I live. So no option that isn't going to require custom fabrication. Fun. Guess i'll have to run my options by an exhaust shop and see what they can create for me since nothing exists that welds/clamps up to the location of the pipes after the secondary cats.

Try welding around the breather hole in the resonator mine cracked and it sounded like glass in my exhaust till it go welded again.
